It's a bit far fetched to say that dropping out of school will automatically lead you to be a Steve Jobs or a Bill Gates.    While Jobs may have dropped out of Uni, he did continue to audit classes for two years AND he'd been attending lectures at Hewlett Packard since he was in junior high. And if it wasn't for buddies like Steve Wozniak who let him sleep on his floor and the support of his adoptive and biological parents (who were all well off and incredibly intelligent themselves) he wouldn't have been able to do what he did.

Fact is, both Gates and Jobs were too smart and too creative at the time to stay in universities that didn't cater to their interests or provide the training neccessary for them to pursue careers in computer programming. They were both better off out of uni and working in the field, which they both did.

Gates scored a 1590 out of a 1600 on his SATS for crying out loud, the man is hardly your average joe.    And his parents were RICH as well. 

Making it without Uni or education requires a combination of intelligence, talent AND familial and social connections that most people don't possess.
